WATERING- SYSTEM.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed February 11, 1916. Serial No. 77,634.

To all whom it may concern: I

Be it known that I, JOHN NoRD vIs'r, a citizen of United States, residing at Angora, in the county of St. Louis and State of ll/Linnesota, have invented certain new and useful Improvements in Watering Systems, of which the following is a specification.

This invention relates to improvements in cattle watering systems and its object is to provide, in connection with a stable, a water reservoir provided with automatic cut-off means whereby a given amount of water will always stand in the reservoir, and further, to provide water troughs in the several stalls which are connected with a secondary tank which is connected to the reservoir and receives a supply of water therefrom which water is conducted to the said troughs and kept at a predetermined height therein by automatic means. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the fol lowing specification, pointed out in the claims and illustrated in the accompanying drawings which form a part of said specification and in which Figure 1 is a sectional plan view of a building showing the application of my watering system.

Fig. 2 is a sectional view in side elevation and is taken on line 22 of Fig. 1.

Fig. 3 is an enlarged vertical sectional View of the automatic regulating device that connects the reservoir with the secondary tank.

Fig. 4 is a cross section taken on line 4 4= of Fig. 3.

Fig. 5 is a similar view taken on line 55 of Fig. 3.

Like reference characters indicate corresponding parts throughout the several views.

To clearly illustrate the application of my invention I show its use in a stableor similar building which is provided with a compartment 1 for the water reservoir 2 and with stalls 3 in which the water troughs 4 are arranged. The several troughs 4 are connected by branch pipes 5 with the main 6 which is, connected by rubber pipe 7 with the secondary tank 8 which is located in the compartment 1 below the partition 9. The secondary tank 8 is supported by a pipe 10 which extends through the partition 9 and through the floor of reservoir and through a nipple 11 secured to the partition 9 and through 'a valve casing 12 which is threaded into engagement with the said nipple and also threaded into engagement with the floor of the reservoir and said valve casing is formed with an annular flange 13 which obtains a bearing upon said partition and upon which one end of a spring 14 rests that encircles said valve casing and that projects thereabove and into engagement with a disk 15 which encircles the upper threaded. end of the said pipe 10 which is projected through the upper end of the valve casing; said disk being retained in any desired position upon the pipe 10 by means of the nut 16.

The valve casing 12 is formed with longitudinal slots 17 and with the valve seat 18 adapted to receive the annular flange 19 of the pipe 10; said pipe below the flange 19 being formed with the apertures 20. In operation the reservoir 2 is provided with a fioat 21 which is connected to the inlet pipe 22 and adapted to close the same at a predetermined water level. The water from the reservoir flows through the opening in the valve casing 12 and when the flange 19 is raised out of the valve seat it will flow through the openings 20 and into the pipe 1.0 and into the secondary tank 8 and from the same through the pipe 7, main 6 and branch pipes into the water troughs. When the water in the troughs and in the secondary tank rises to a certain level its weight will be sufficient to draw the pipe 10 down against the tension of the spring M until the flange 19 occupies the valve seat 18 and cuts off the flow of water to the tank 8. The fact that the disk 15 may be adjusted upon the pipe 10 permits the water level in the tank 8 and troughs 4 to be altered as desired.

What is claimed is 1. A watering system comprising a reservoir, a tank therebeneath, a water pipe connecting said reservoir and tank, a slotted casing encircling said water pipe within said reservoir, valve connection between saidcasing and water pipe whereby water may be admitted to the latter member and means connecting said casing and water pipe whereby they are yieldingly retained in adjusted position to keep said valve connection open.

2. A watering system comprising a reservoir, a tank therebeneath, a water pipe connecting said tank and reservoir, a flanged slotted casing encircling said water pipe Within said reservoir, valve connection be:-

tween said casing and Water pipe whereby as my oWn I have hereto affixed my signa- Water may be admitted to the latter member,' 'turein the presence of tWo subscribing Wit- 10 a disk adjustably carried by vsaid Water pipe. messes. above said casing and a spring encircling said casing and bearing upon the flange thereof and upon said disk to yieldingly re Witnesses: tain saidjvalve connection open relation. VANCE MAKI,

In testimony that I claim the foregoing L. BURGHARDT.
